IMPROVEMENT IN cHuRNs.

Specification forming part of Letters Patent No. 133,878, dated December10, 1872.

To all whom it may concern:

Beit known that I, MYRON MOSES, of Malone, in the county of Franklin andState of New York, have invented a new and Improved Churn; and I dohereby-declare the following to be a full and exact description of thesame, reference being had to the accompanying drawing forming part ofthis specilication, in which- Figure lis a perspective view of the wholemachine; Fig. 2, a detached elevation of the two sets of beaters,collar, and shaft; Fig. 3, a detached plan of the upper set of beaters;and Fig. 4, a detached vertical section of the mechanism for driving thedasher.

Similar letters of reference in the accompanying drawing denote the sameparts.

This invention belongs to that class of churns which employ two sets ofbea-ters revolving in opposite directions; and has for its object toimprove the constrction of such a churn in such manner, first, that themechanism for driving the churn may be readily removed with thechurnffrom the holdin g-frame; and,

. second, thatthe cream maybe thrown to the sides of the churn duringthe operation of churning. To this end the invention consists,

lfirst, in the construction and arrangement of that part of the framewhich supports the' driving mechanism of the churn.; Second, in `1the-construction of 4the beaters.

In the drawing, A is the churn, the same being of sheet metal, ofordinary construction,

.and placed, when the process of churning is going on, upon the iioor Bof a frame, C C', `which door has a recess, ,of. a shape to beaccurately fitted by the churn, said recess having inclined sides toreceive the flange on the bottom of the churn and prevent'its movingupward. The parts C C are connected by four or more pairs of parallelmetal bars, D,

each of which is in contact at its ends with two of its fellows, thejoints being all mitered so as to make the bars D serve as braces to.each other as well as the posts. One of the churn. VThe pivoted bar hasa pin projecting inward'from its free end, which pin, when the bar isturned down, enters a notch, e, in the top of the post C, whereby thisbar is fastened hub bears aflat inclined beater, F, and a semi-` conicalbeater, F1, attached to the end of a radial arm extending from theopposite side of the hub from the beater F. Resting on the hub E1 isanother hub, E2, rigidly attached to the lower end of a collar, G,placed loosely on the shaft E. The hub E2 has radial armse'extendingfrom opposite sides, to the ends of which are fastened beatersF2, which are of the same shape as the beater F1, except that they aredished out on the inner sides, as Shown at k, Figs. 2 and 3, in orderthat they maythereby throw the cream toward the sides of the churn, andalso that there may be room enough between the hub and beaters to workin while cleaning the latter. Gonical beaters pass through the creamwith less resistance than at ones, and consequently to work themrequires less power. At the Same time, by the squareness of their rearends, my conical beaters agitate the cream so much as to require butcomparatively little churning. As shown in Fig. 2, there is a groove inthe top of the hub El, next to the shaft E, which groove the lower endof the collar G enters. By this arrangement cream is prevented fromgetting between the collar and shaft E. At the top of the shaft E isa'miter-wheel, H2, similar to a miter-wheel, H1, on the upper end of thecollar G, which'wheels form a bevel -gear with a miter-wheel, H, placedon the end of a shaft, I, supported in suitable boxes attached to thetop of the frame, and at the opposite side thereof from thepivoted barD, so

as not to be in the way of moving the churn. By means ofthiSbevel-gearthe upper and lower sets of beaters are whirled inopposite directions. shaft an arm, I1, extends upward, at the top ofwhich arm is a socket, l?, Fig. 4,through one side of which extends ascrew, l. In the socket I is placed a bolt, K, having a flange, m,resting on the top of the socket, a circumferential groove, a, near theflange and a longitudinal groove, o, communicating at its PATENTOFFICE..

From one of the boxes of the p upper end with the groove n, and at rightangles with it. The point of the screw l is elv ways in one or the otherof these grooves. The bolt K has at boss, k1, at its lower end, and :tliange, k2, concentric with `the boss and sepa,- ra-ted from it by agroove. The boss k1 enters :t depression in the head of the shaft E, andthussteadies the latter. When this is the case the screw lis in thegroove n, and the bolt K should be turned so as to bring the groove oout of line with the screw,which then locks the bolt K. By turning thebolt so as to bring the groove u in line with the screw, the bolt cenberaised, the screw traversing the groove n. The shaft E is then11nsupported at the top, and, together with the in described.
